Servers :: Can I Open Port On Ubuntu 9
Oct 11, 2010I can seem to open port 25565 for a java application (executable jar)
I'm running ubuntu server 9 thoroughly up to date code...
Yet connections to port 25565 fail when I have the firewall enabled (sudo ufw enable)
For example canyouseeme.org says "Error: I could not see your service on port (25565) Reason: Connection timed out"
And connections to port 25565 _DO WORK_ when I disable the firewall (sudo ufw disable)
canyouseeme.org says "Success: I can see your service on port (25565)"
Ubuntu Servers :: Ssh Is Running But Port 22 Not Open
Jul 10, 2010I have two computers on a LAN. (This is history not a Bazaar question, although I have one of those too) One of them (Ubuntu 9.04) Im using as a Bazaar repository over sftp. Its been working fine for about a year. Then we had a thunderstorm that knocked out our Internet service for a couple of days. When it came back up everything is working fine accept I could no longer commit to the server. A little detective work showed that ssh was not running on the server. I started it and Bazaar then couldnt find the repository files. I still suspected an ssh problem, but port scans from both computers showed port 22 open on the server and I could do a ssh login from the client ok. Then I started fiddling with ssh on the server and now I have ssh problems on top of the Bazaar problems.
On the server I deleted then regenerated the ssh keys. Ive done
sudo /etc/init.d/ssh reload
sudo /etc/init.d/ssh start
I get a normal starting message and ps ef |grep ssh
shows /usr/sbin/sshd running. But the port scan does not show 22 open and I get connection refused at the client.

Feb 2, 2010I am configuring an internal only IMAP server for archival emails. I am absolutely baffled why my connection is being refused. UFW is disabled and IPTABLES has a rule to allow all connections on 143 and 993. When I telnet this response is given:

Oct 11, 2010Strange issue here when trying to verify firewall on Server 8.04. No ftp service running at all on server, but both nmap and netcat report port 21 as being open, even though it isn't.I am 100% sure that port 21 is not actually accessible and iptables rules are fine. Trying to connect to the port fails, yet nmap and netcat seem to report a "false positive"?Have also checked on a number of other servers I'm running, and this "false positive" seems to apply to all of them.

Ubuntu Servers :: Use Xinetd To Start Svnserve?
Jan 30, 2011I am trying to run svnserve on startup on an Ubuntu Server 10.04 machine using xinetd
My repositories are at /home/svn, so the directory should be the same as in the example. Following the example, the owner should be www-data, I assume. (Is that right?) I've also tried the admin user account as as the svnowner (the one used to set the svnserver up).
I've never done any shell scripting, so I tried xinetd instead of using the startup script. But if I don't get any feedback for using xinetd that will be my next course of option.
For reference, the link above suggests adding
Code:
svn stream tcp nowait svnowner /usr/bin/svnserve svnserve -i -r /home/svn
to the /etc/inetd.conf file, replacing svnowner and /home/svn to the appropriate values (although I'm not 100% sure what those should be). I assume since I did a chown on the repo to www-data that www-data is the owner I need to put in that line, but it doesn't work.
It's just annoying to have to ssh in and type
Code:
svnserve -d --foreground -r /home/svn
every time I reboot.
Ubuntu Servers :: Kerberos - LDAP - NFS ?
Feb 7, 2011I've currently got Ubuntu server configured so that clients can login using LDAP user accounts that I've created using ldapadduser (from the ldapscripts package).
I've also got NFS exports working so that /home can be exported to clients. Kerberos authentication is enabled for NFS and clients require a nfs/clienthostname.domain principal to be able to mount the NFS share.
However, I now realise that for LDAP users to be able to access the mount they need their own Kerberos principal. If I run kinit dan@DANBISHOP.ORG then I can access /home/dan as user dan otherwise I get permission denied.
My question then is how best to proceed... is there a way to configure the client/server so that once a client has mounted the nfs share using Kerberos, all users can access it without their own principal?
It seems more usual to create kerberos principles for all users, but then how does one manage users? Using ldapscripts is very easy, but if the admin then has to manually create kerberos principals everytime, it could become very tedious. Furthermore how do users change their password if kerberos is used for authentication?
Ubuntu Servers :: CANNOT Change Password, Kerberos + LDAP?

Fedora Servers :: Sshd Within Xinetd Doesn't Work
Aug 21, 2010I recently installed Fedora 13 on VMware 7 environment without X window. sshd did work fine, but when I tried to put it into xinetd, it doesn't work any more. Here is what I have done so far :
I stopped sshd. #service sshd stop
and I configured xinetd.conf like below.
Quote:
#
# This is the master xinetd configuration file. Settings in the
# default section will be inherited by all service configurations
# unless explicitly overridden in the service configuration. See
# xinetd.conf in the man pages for a more detailed explanation of
# these attributes.
[Code]....
I don't know what I did wrong with them. I configured xinetd.conf, and I made service configuration file 'ssh' in /etc/xinetd.d, and I restarted xinetd.
What am I supposed to do to make a life on my sshd within xinetd ?

Server :: Open SMTP Port On Router (which Connects LAN To Internet) Also Needs To Open?
Apr 14, 2010I have sendmail running on my centOS 4.6. My lamp server also runs on it. I want to send mail through php mail function. when i execute php page, which fires the mail function, it takes so much long tim1 say even 1 minute, and at last displays that message sent successfully. Suppose, destination address is [URL].... I did not get any mail there. My server is running in LAN. I checked the status of sendmail, it shows me that it ios running. when i issue "nmap localhost" it shows me that SMTP port 25 is open, but when i issue "nmap myserver" (192.168.1.20 myserver ( written in hostfile)), it does not show that SMTP port is open.
I checked the /var/log/maillog, one person in my previous post advice me to see that. There it shows that message is accepted for delivery...but i do not get any mail in my destination, even not in spam folder. One more confusion is that, in my case my server is in LAN and if I am at all enable to open the SMTP port on it, does i need to open SMTP port on my router (which connects my LAN to internet) also needs to open? I think no, because SMTP is application layer protocol, it will wrap my mail in IP packet, which router just need to forward. am i right?

May 23, 2010I just installed apache.

Apache is working locally (I get the `it's working' screen at [URL]). However, I cannot access my computer from an external computer by going to [URL], which is equivalent to [URL] -- [IP address changed slightly for privacy] Here is a screenshot to my router settings. I disabled the filter for port 80 on the router. here shouldn't be a firewall, unless it's automatically installed with ubuntu 10.4. (sudo ufw status says `inactive'.)
I checked my ports from [URL] and indeed port 22 is open (ssh-ing into my computer externally is not a problem), whereas port 80 is closed. What step in opening up port 80 am I missing? (I also made sure my ISP isn't blocking port 80.)
